Log:
Revert r310138
Adding %b support to vfprintf for parity with kernel space requires
more discussion/review.
In particular, many parties were concerned over introducing a
non-standard format qualifier to *printf(3) which didn't already
exist in other OSes, e.g. Linux, thus making code which used %b
harder to port to other operating systems.
